ELECTRIC SIGN.

Specification of Letters Patent.

Patented July '7, 1914.

Application filed April 5, 1913. Serial No. 759,008.

To all whom it may concern Be it known that I, MORTIMER Nononu, acitizen of the United States, residing in the borough of Manhattan,city, county, and State of New York, have invented an Improvement inElectric Signs, of which the following is a specification.

Heretofore as far as I am aware, electric signs employed for advertisingand other purposes have been so constructed as to comprise a frame orshell in which there are a plurality of lamps, and which when lighted atnight, set forth the outline of the design, and in order that such signsmay be the more readily intelligible during the daytime they have, I amaware, been provided with exteriorly extending flanges which have beengilded or painted various colors to make the sign more intelligible inthe daylight. The exterior flanges which have been employed in electricsigns however, have not enhanced or been the means of enhancing theappearance of the sign at night, and the object of my invention is toprovide an electric sign so constructed that the flange or flangesemployed to make it the more intelligible in the daytime, are alsoutilized to bring out its form and configuration and enhance the effectof the sign when lighted at night, as will be hereinafter moreparticularly de scribed.

In the drawing, Figure 1 is a perspective view of the letter I embodyingmy present invention. Fig. 2 is a longitudinal section thereof, and Fig.3 is a cross section on line a, .r, Fig. 2, Fig. Qbeing a cross sectiontaken on line y, 3 Fig. 3.

Referring to the drawing, it will be understood that while I have shownthe capital letter I for simplicity of illustration, I do not limitmyself to this particular letter or any other letter or any form orconfiguration of electric sign in which my invention may be employed.

In the drawing, 10 represents the base, which as will be understood, maybe made of any suitable material. As illustrated, the letter I may beformed of a frame made of sheet metal or any other suitable material,one edge of which is connected to the base 10 in any suitable manner,the frame being open at the edge opposite to that at which it is securedto the base, and in the letter shown comprises the sides 11 and the ends12. The free edge of the frame is provided with a flange indicated at 13which extends inwardly and at any desired inclination. As will beunderstood, in suitably spaced positions in the base 10 there areelectric lamps indicated at 14:.

The mose advantageous relationship between the position of the lamps andthe flange 13,that is to say,the position in which to obtain the besteffect, is to so arrange the lamps and the depth of the frame that theends of the lamp filaments 15 are placed substantially on a line withthe free edge of the frame and the central portions of the lampfilaments on a line with the free edge 16 of the flange 13.

As is customary, the inner surface of the frame as well as the face ofthe base, may be colored or painted in any suitable manner, and also theflange may be gilded or otherwise colored. In the daytime this internalflange is readily discernible to outline the character or design of theadvertisement and when the lamps are lighted at night, a portion of thelight will be thrown against the outer surface of the internal flangeand reflected therefrom, while other portions of the light will bethrown against the face of the base and the inner sides of the frame,and reflected therefrom, making a sign having a varied colored effect.

I claim as my invention:

An electric sign comprising a base, an open sided frame connected to thesaid base and forming a character to be displayed, an inwardly extendingflange secured to the outer edge of the said frame and a plurality oflamps fixed in the base within the frame in such positions that the endsof the lamp filaments are substantially on aline with. the free edge ofthe frame, and the central portions of the lamp filaments substantiallyon a line with the free edge of the said flange.

Signed by me this 24th day of March, 1918.

MORTIMER NOR-DEN.
